[lldb][swift] Only run Swift API tests when Swift support is enabled

Disabling Swift support in LLDB doesn't prevent the test suite from running
the Swift tests (which then end up failing instead of being marked as
unsupported). This adds a lit feature for Swift and adds the REQUIRES to all
Swift tests to mark them as unsupported if Swift is disabled.
